Figure 2. Botulinum toxin injection for crow’s feet. It is important not to extend medial to the mid-pupillary line to avoid lower lid ectropion. Lateral injection should be placed approximately 1 cm lateral to the lateral canthus. Volumes referenced are independent of neurotoxin variety and assume dilution as specified in the body of the text (i.e., 1 mL saline per 100 unit vial of Botox® or Xeomin® and 3 mL per vial of Dysport®). While these figures offer a guide, dosing may vary between patients according to their musculature and anatomy
